I'm currently trying to install grapheneOS in a New Pixel 6a using the Web Installer with my current Pixel 3XL. During the flashing process i geht the following error message:
Error: The requested file could not be read, typically due to permission problems that have occurred after a reference to a file was acquired.
It comes pretty late in the flashing process. (In the fastbootd screen)
I also tried my Desktop PC ( popOS and Google Chrome) but there i geht a USB error.
Thanks for any advice
